A liquid ejection device ejects liquid droplets from a liquid ejection head. The liquid ejection device includes a liquid feeding member that feeds liquid to the liquid ejection head. The liquid feeding member is connected to a liquid ejection head to feed liquid to a common liquid chamber of the liquid ejection head, which liquid ejection head includes the common liquid chamber that supplies the liquid to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets. The liquid feeding member includes a liquid circulation path through which the liquid circulates in a direction parallel to a direction in which the nozzles of the liquid ejection head are aligned.

An ink cartridge removably mountable in an image forming apparatus includes a flexible storage member, a pressurization-space formation member, an output port, and an opening-and-closing assembly. The flexible storage member stores ink. The pressurization-space formation member hermetically houses the storage member and forms a pressurization space to which a fluid is supplied between the pressurization-space formation member and the storage member. The output port is connected to the storage member, through which the ink is supplied from the storage member to the image forming apparatus. The opening-and-closing assembly opens and closes between the output port and the storage member by the fluid supplied into the pressurization space.

An image forming apparatus includes a recording head, a head tank, an exhaust unit, and a suctioning device. The head tank has liquid chambers with exhaust ports. The exhaust unit includes an exhaust channel connected to the suctioning device to exhaust air from the head tank, an exhaust chamber connected to the ports of the liquid chambers, a valve member to collectively open and close the ports, a valve driving chamber communicating with the exhaust channel and having a flexible member forming a wall face thereof, a valve driving member disposed at the flexible member to open and close the valve member, and a choke channel communicating the exhaust chamber with the valve driving chamber. When the suctioning device suctions air through the exhaust channel with the liquid being in the choke channel, a volume of the valve driving chamber contracts and the valve member opens the ports.

A liquid discharging-type image forming apparatus capable of securely eliminating mixed air bubbles from the ink liquid and forming a stable image. The apparatus includes: a sub tank 35 of which negative pressure amount is detected; a pump 115 sucking ink when the detected amount of the sub tank 35 is lower than a predetermined amount so that the sub tank 35 and recording heads 34 have negative pressure; a second backflow prevention unit 203 to stop the sent ink to be reserved in a second liquid container 201, which is pressurized as ink increases. When the ink is again filled in the sub tank 35, the ink is sent from the second liquid container 201 before being sent from the first liquid container. Accordingly, ink is not accumulated in the second liquid container 201, allowing the second liquid container 201 to be smaller and the image forming apparatus as a whole to be more compact.
